摘要： A method for producing a bonded rare-earth magnet according to an embodiment of the present invention includes the steps of: providing a rapidly solidified rare-earth magnet alloy powder; providing a solution in which a resin that is in solid phase at an ordinary temperature is dissolved in an organic solvent; mulling the rapidly solidified rare-earth magnet alloy powder and the solution together and vaporizing the organic solvent, thereby making a bonded rare-earth magnet compound in which magnet powder particles that form the rapidly solidified rare-earth magnet alloy powder are coated with the resin; making a compressed compact by compressing the bonded rare-earth magnet compound under a pressure of 1000 MPa to 2500 MPa; and thermally treating the compressed compact. If the rapidly solidified rare-earth magnet alloy powder to be mulled is 100 mass %, the solution includes 0.4 mass % to 1.0 mass % of the resin and 1.2 mass % to 20 mass % of the organic solvent.
